WARNING: Do not over-tighten, as this may lift the
lever and cause the auger drive to be engaged without
depressing the auger drive control.
1. With the auger drive control lever released, the hook (A A, Figure 29)
should barely touch the lever (B B) without raising it. There can be a
maximum of 1/32" (0.8 mm) clearance.
2. To adjust, loosen the nut (C C) by holding the adjusting flats (D D) and
turning the nut. Then, turn the adjusting flats and hold the adjust-
ment screw (EE). The adjustment screw is a phillips screw and the
head can be held or turned by inserting a screwdriver through the
spring (FF).
3. Hold the adjusting flats and tighten the nut.
4. Start the engine and check the auger. The auger must not be engaged
unless the auger drive control lever is depressed.
5. With the engine running, fully depress the auger drive control lever.
The auger should engage and run normally.

belt may require an adjustment (see “Belt Adjustment” section).
